ADJUSTABLE PROTECTING DEVICE FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent N o. 675,398, dated June 4,1901.

Application filed February 28| 1901. Serial No. 49,214. (No model.)

To @ZZ whom t may concern.-

Be it known that we, EDWIN J. MOALLIs- TER, ALMOND. PAGE, and LoUIs C.WERNER, citizens of the United States, and residents of Newark, in thecounty of Essex, State of New Jersey, have invented certain new anduseful Improvements in Adjustable Protecting Devices for Electric Lamps,of which the following is a specification.

Our invention is an improvement in electric lamps employed for signs,letters, iigures, and designs, such as that shown and described in theLetters Patent issued to W. F. Brewster December 11, 1900, No. 663,532.

The object of our invention is to provide a cheap and effectiveadjustable device to pro,- tect exposed lamps and their connections fromrain, snow, and dampness.

We provide a rain or weather guard for each lamp, consisting of acylinder of sheet metal, like brass, (but any suitable material may beused.) One end of this cylinder encircles and is adjustably supportedupon the lamp socket or receptacle. There is a clamping device to fixand hold the cylinder in position on the socket. .f The other end of thecylinder is turned inward and stands at an acute angle, its edge beingresilient. This edge is circular and is capable of engaging with thecylindrical tapering surface of the lamp-globe, while the line ofcontact with said globe may be caused to vary by sliding the cylinder upor down upon the socket or receptacle, thus providing for adjustment tolamps having globes of dierent diameters.

The accompanying drawing illustrates our invention. It is a verticalcentral section of the lamp-socket, receptacle, and weatherguard.

s represent the lamp-socket a'nd receptacle, and 2O is an incandescentlamp having two termin alcontacts 21 22. In the socket s there arecontacts 23 and 24, engagingwith the contacts 25 and 26 in the part t.There is a central perforation in the parts s t, through which passesthe bolt 27, clamped by the nut 28. Thus the two parts s and t aremechanically there is a clamping device having ears like 31, with a bolt32, so that we may slide the cylinder up and down on the socket s andclamp it in any position with the screw 32. There is an inturned ilangeor collar h, Xed to or forming part ofl the cylinder at its oppositeend. The internal edge of this collar h is slightly resilient andpresents a circular outline, so that it may be caused to closely engagethe surface of any lamp globe or globes differing in diameter Withinreasonable limits.

What we claim, and desire to secure by Letters Patent, is

l. A socket or receptacle for an electric lamp and a lamp, combined witha cylindrical section of sheet metal having its upper edge bent inwardto engage the surface ofthe lampglobe and means for clamping thecylinder in position.

2. In combination a lamp, a socket or receptacle therefor, aweather-guard consisting of a sheet-metal cylinder having its upper edgefolded to engage the lamp-globe and means for fixing said cylinder inposition.

3. The combination yof an incandescent lamp, a suitable supporttherefor, a weatherguard consisting of a cylindrical section of sheetmetal having its free edge turned inward to engage the lamp-globe andmeans for adj ustably iixing said guard in position.
